Be it knownthat I,EDwARn D. Soi-unir., a citizen ofthe United States,residing zit-Brooklyn, in the county of Kings and State oiNeW Yorl,'have invented` certainnew and useful Improvements in Sealing# Headsfor Bottle-Sealing Machines, of which-the `followingis a specification.f i

'lhisiinvention relates to :improvements ini-sealing lheads for use inmachines for applying bottle caps,

whereby the flange of the cap is crimped, pinched orl indented atintervals into lockingA engagement `with-a locking;` surface orshoulderon a bottle.

I do not deem it necessary to :illustrate other parts of a machine forapplying the seals, and it will be un derstood that the head about to bedescribed may be employed with any suitable mechanism by which it l willbe depressed or a bottle seat raised with relation tothe head, to getthe desired sealing pressure, it being 'immaterial to this invention,whether the head is depressed, the seat raised7V or whether both partsare moved toward each othezgso long as the required seal- ,ing pressureis brought about.

In the drawings: Figure l is a central section or' a ,sealing headembodying my invention, with a bottle cap in dotted lines in. the' sealholding cavity therein; lFig. 2 is an enlarged sectional View of thelower part "-of thehea'd, showing the parts in about the position they y"assume at the time the seal is locked on the bottle, the fupper portionof a bottle witha seal thereon being shown in section; and Fig. -3 is 'abottom plan view ottheplungen partly broken away to show the arrange-`4`mentof `the seal lockiirgpins4 or devices and the pins fortemporarily hdldi'ng the cap, preparatory to the sealing operation` i Yf Referring to thedrawings,l the numeral l designates the head casingformed preferably two sections 2 and .3. lhe upper portion of the'casing is threaded externelly near its lower end as indicated at 4 forthe recep'` ,'tionof the internally threaded upper Wall of the largerlower part'oi the casing, thus soiconneeting the parts that they may bereadily separatedor put together inl getting access to the interiorparts, or in assembling said 'pai-ts. `The lower portion of the casingis rabbetedas ,indicated at 5, thusiorming` a narrow shoulder 6 upon heroundin-gor cam surfaces 9 of a plurality oi radla'lly arrangedlaterallymovable seal locking devices i I0. The'seal'loeking devices areformed of two telescoping cups,` ltihe parts of which are adapted tomove togetherpagainst theinluence of springs 1l, one of hich shoulder isseated a ring 7 presenting a bevelen 4camsurface 8, vwhich surface issimultaneously engaged are bored vout sufficiently as shown 9.1516, toperint `tl1Q,- outer cupsto movexinto said recesses when the f movedupwardly.` The plunger is limited in its downward movement by a ledge417l onthe lower partei the` ont@ casing and is formed witha hollow`eit'tension 18,'which4 extends a short distance up into the upper-partofftl-ie` casing. Between this jextensenand Ythe screw, il?) isinterposed the sealing' `spring v20.l y i The numeral 2l designtesascrew pligwhe r efi,

set screw 24 by which theplug maybesecurely lield in 70 l adjustedposition.' It will be'seen thatby adjusting the "5 screw plug 21, eitherup or downfas the exige'cies of the case may require, the sealingpressure exerted upon the cap and bottle' will be varied, as well as thepoint'of engagement between the seal indenting' points of the 75 ylockingr devices and cap flange. l

Between the seal locking devices Iprovide antunber of recesses`25, shownin Fig. 3. lThese contain sprintf-,backed pins 26, whose forward endsextend slightl through the interior wall rofthe plunger into the sealcavity and are for tlfe purpose oi temporarily holding the seal. Therecesses for these springs and pins are closed by screws or plugs`27against which the outer ends ofthe springs abut.

In operation, the head is depressedftoward'a-bottleiflgi whichmay besupported upon an 'suitable seat, or the bottle and seat. may'beraisedtoward the head, and in. either event, the plunger will bemovedupwardlyinl thecasing against the influence of the senlingspring,4 'I "and asthe plunger sormoves the rounding cam surfaces 9()` `9 of the seallocking devices will simultaneously eng-agen ,the bevelor cam surface ofthe ring .7, forcing said Y devices yieldingly inward projecting thepins into` engageu'ient with the flange of the bottle cap, indenting itat intervals into locking engagement with the shoulder onthe lmttlek a M"ffltlodilcations' in the described construction Amay be madofwithinthespirit of this inventionfendfwhile I, have vdescribed the sealinghead as especially adapte vfor applying hard metal flanged caps tObottles having an annular locking surface or shoulder adjacent to their,mouths, it will be understood that the heads wouldbel f equally adaptedfor applying caps or covers to vessels )j other than bottles,isuclx asglass jars, cans, etc., it being' obviously 'only necessary to vary thedimensions of the' 105 head parts to accommodate them to such additionaluses. .i 4 In orderto return the'pin carrying part of each seallocking'device to normal position, I preferably employ a. spring 28 forthe `pin carrying part of each locking de? 11.
